LEWIS T. HOUGI-ITON, OF WORCESTER, MASSACHUSETTS.

CREEL-SUPPORTING RAIL FOR SPINNING-FRAMES.

To all whom it may concern:

Be it known that I, LEWIS T. IIU'UGIITO'N, a citizen of the UnitedStates, residing at WVorcester, in the county of lVorces-ter and Stateof Massachusetts, have invented a new and useful Creel-Supporting Railfor Spinning-Frames, of which the following is a specification.

This invention relates to that class of spinning or twisting machineswhich draw the materials to be spun or operated upon from verticallyjournaled creels or spools.

The especial object of this invention is to provide a strong, simple andinexpensive support for the supply spools or creels which will avoid theuse of wooden supports, which will provide a construction which may bereadily cleaned, and which will have the bearings for the creels orspools so arranged that the spools or creels will not be liable to crampor bind.

To these ends, this invention consists of a metallic construct-ion forsupporting the supply spools or creels of a spinning or twistingmachine, of a special construction for securing the porcelain or similarbearings therein, and of the vcombinations of parts as hereinafterdescribed and more par ticularly pointed out in the claims at the end ofthis specification.

In the accompanying drawing, Figure 1 is a perspective View ofsufficient parts of a spinning or twisting machine to illustrate theapplication of my invention thereto. Fig. 2 is an enlarged sectionalview of one of the step-bushings with the porcelain bearing-piece packedtherein. Fig. 3 is a fragmentary view showing one of the step-bushingsforced into place in the step-rail. Fig. 1 is a perspective view of theparts illustrated in Fig. 2, and Fig. 5 is a sectional view of amodified form of bearing.

In that class of machines to which this in" vention relates, the supplyspools or creels have heretofore been secured between shelves formed bywooden planks or boards. The use of these wooden creel-boards I havefound to be objectionable, as it is ditlicult to keep the wood-workclean after the same has become saturated or filled with oil; while inmany cases, the creel-boards are liable to warp or twist, so that thecreels may be cramped or restricted in their bearings. In some of themachines of this class the steps or pivots for the creel-spindles aremade of porcelain or similar material.

Specification of Letters Patent.

Application filed April 27, 1903.

Patented Apr. 2, 1912.

Serial No. 154,412.

These porcelain bearing pieces have ordinarily been simply fitted intoplace in the wooden creel-boards, and in practice, I have found that theshrinkage of the wooden creel-boards frequently permits the porcelainbearing-pieces to be loosened and displaced. To overcome theseobjections I have provided an entirely metallic creelsupportingconstruction for machines of the class referred to, in which instead ofemploying wooden creel-boards, I employ compa 'atively narrow metallicstep-rails, each of which is preferably of an angular or flangedconstruction, and I have also provided improved means for fasteningporcelain or similar bearing pieces in place in the step-rail.

Referring to the accompanying drawing for a detail description of aconstruction embodying my invention, 10 designates metallic uprightswhich extend up at intervals from the frame of an ordinary spinning ortwisting machine. Riveted on the uprights are angles 11 which form thecross ties for supporting the perforated creel boards or creel-rails 1.3and 14. Each of the rails 13 and 1 1- is preferably of a reinforced orflanged construction in order that comparatively thin stock may beemployed. In the present instance, the rails 13 and 14 are substantiallyL-shaped in cross-section, although, if desired, other cross-sections ofrailing may be employed, it simply being advisable that the rails havelat sections for receiving the bearings and one or more stiffeningflanges. Pressed into place in the upper rail 11 are bushings or tubes15 which receive the upper ends of the spindles of the creels C. Theparts which form the steps or bearings in the step-rail 13 are combinedin such a manner as to efficiently fasten the porcelain step-pieces inplace. In order to accomplish this purpose for the lower end of eachcreel spindle, I employ a metallic bushing or tubular member 16 which ispreferably of slightly tapering form, and I fit into the barrel wall ofthe upper end of the bushing or holder 16 a porcelain bearing piece orskewer step 18 which is surrounded by a yielding lining or packing 26 ofblotting-paper, leather or other compressible material. These bushingsare inserted in skewer step perforations in the lower creel rail.

The parts are assembled as illustrated in Fig. 2 before the bushing isforced into place in the step-rail, and the parts are so proportionedthat when the metallic bushing is forced into its bearing in thestep-rail 13, as shown in Fig. 3, it will be contracted, exerting asubstantially uniform pressure upon the porcelain steppiece toefficiently fasten the same in place.

In practice I have found that when it is attempted to apply pressure toa porcelain step-piece from one side that the porcelain is liable tocrush or be fractured, but when a porcelain bearing-piece is fitted intoa holder or bushing, the bushing may be contracted to exert heavypressure around the entire periphery of the porcelain bearing piecewithout the liability of crushing or breaking the same. I regard this asa particularly important feature of my invention, as by assembling theparts in this manner, I have provided means for fastening or looking theporcelain step-piece securely in position. Where several tiers of creelsare used, as is sometimes the practice in machines of this class, thelower ends or depending tubular parts of the bushings 16 will formbearings, chambers, or top holders of reduced internal diameter forreceiving the upper ends of the next lower series of creels. Supportedfrom the step-rail 13, I may provide the ordinary guide-rod 19 overwhich the threads are drawn.

In Fig. 5 I have illustrated a modified step or bearing piece in whichthe upper end of the tapering bushing 16 is closed and is slightlydepressed or dished down. When this form of step is used, I preferablyform the same from sheet steel, and I harden the bearing surface orupper part of the bushing so that the same will not speedily wear out,although in practice, I prefer to use the composite bearing in which theporcelain step piece is inclosed within the sheet metal bushing.

I am aware that numerous changes may be made in practicing my inventionby those who are skilled in the art without departing from the scopethereof as expressed in the claims. I do not wish, therefore, to belimited to the construction I have herein shown and described, but

What I do claim and desire to secure by Letters Patent of the UnitedStates is 1. In a spinning or twisting machine, the combination of acreel rail having perforations, a tubular bushing having an outwardlytapering upper portion secured in each of said perforations and heldtherein by friction, and a step-piece held by friction in each of saidbushings.

2. In a spinning or twisting machine, the combination of supports oruprights, a creelrail mounted thereon and having perforations, and atubular member having an outwardly tapering upper portion secured in oneof said perforations by being forced longitudinally into place thereinand being of suflicient size to cause the same to be held solely by thefriction produced when it is forced into said perforation, said tubularmember having a rigid bearing thereon.

3. In a spinning or twisting machine, the combination of a creel-rail,metallic bushings, a step-piece of porcelain or similar material fittinginto each bushing, and held in place therein by the pressure of thebushing caused by forcing the same into place in the rail.

4-. In a spinning or twisting machine, the combination of a metalliccreel-rail, metal lic bushings, a steppiece of porcelain or similarmaterial, and a packing fitting into each bushing, said packing andstep-piece being secured in place by the compression of the bushingcaused by forcing the bushing into the rail.

5. In a spinning or twisting machine, the combination of end supports oruprights, a lower creel rail consisting entirely of metal carried bysaid supports or uprights and having perforations extending entirelytherethrough, and metallic tubular members flared outwardly at theirupper ends, each extending through one of said perforations projectingabove and below the metallic rail and frictionally secured therein, andeach having a fixed hearing at the top for a creel spindle.

6. In a spinning or twisting machine, the combination of end supports oruprights, a lower creel rail consisting entirely of metal carried bysaid supports or uprights and having perforations extending entirelytherethrough, and metallic tubular members flared outwardly at theirupper ends, each extending through one of said perforations projectingabove and below the metallic rail and frictionally secured therein, eachhaving a hearing at the top for a creel spindle, an upper all-metal railcarried by said end supports or uprights independently of the lower railand having perforations therethrough, and metallic tubular members inthe last named perforations for the upper ends of the creel spindles.

7. The combination with a metallic creelrail provided with a skewer-stepperforation, of a yielding lining under pressure in said perforation anda skewer-step frictionally held by said lining.

8. The combination with a sheet-metal creel-rail, perforated to receivea skewerstep, of a holder having means for securing the same within saidperforation and having its barrel wall inclined relatively to theskewer-step therein so as to produce frictional engagement therebetween.

9. In a creel, the combination of a perforated creel-board, a holder fora skewer-step co-axially mounted with respect to a perforation thereofand provided with a depending tubular part forming a top-holder for thetop of a lower skewer.

10. In a creel, the combination of a perforated creel-board, askewer-step holder secured Within a perforation thereof and having apart depending co-axially below the said perforation and forming a topholder for a'lower skewer.

11. In a creel, the combination of a perforated sheet-metal creel-board,a skewerstep in a perforation thereof and a tubular holder for saidskewer-step having an extension providing a chamber of reduced in ternaldiameter depending below said creelboard.

In testimony whereof I have hereunto set my hand, in the presence of twosubscribing witnesses.
